I bought the Propet Voyager this summer for an extended trip. They work perfectly for around camp, and can be expanded to fit multiple layers of socks if you feel the need (or the skeeters are getting to you)
I wouldn't recommend them for river crossings on fast-moving or big rivers, as the straps are not that great at holding onto you in thick mud or while kicking.
However, they are comfortable enough and thick enough that you don't feel most rocks, and can wear them for hours.
Checked out a pair of Prophet Voyagers when on holidays this summer and was surprised how light and comfy they are. I'm going to try again here in town, see if I can find my size. They're a bit pricy at $45 or so, but now that fall is here...maybe I can find some on sale.
I also was going to check out some cheap surf booties for cooler climates or where it may be a little wet.

The Sprint Aquatics run small; to wear over socks you need to order a size larger.
I use them only for going in and out of the tent at night, and only because my hiking shoes tear up the ground outside the tent door. That's the only reason I even take them--my trail runners are so comfortable I don't need camp shoes otherwise.
My next trip, I get to try out my new Goose Feet with the waterproof over-booties!
